Oddball links for BSD this week – but pay attention to the first one.
BSDNow 164 has a whole lot of conversation about things that start with V, plus an interview with Josh Paetzel of iXsystems about the upcoming MeetBSD, FreeNAS and other things.
If you are using em(4) or re(4) devices for networking, you may want to turn on polling. MSI may or may not help for re(4), along with switching to the emx(4) driver.
Remember I posted that LibreSSL is in base DragonFly, but not default? Well, it’s default now. You can have a system without OpenSSL at all, by rebuilding DragonFly-current and using up-to-date dports.
Update: see John’s comments for clarification: LibreSSL is default; the change is that OpenSSL isn’t even built any more. The result is still the same good news: you can have an OpenSSL-free DragonFly system now.
I should have posted this sooner: SemiBUG is having a meeting in about half an hour at Altair Engineering. Mike Wayne is presenting about monitoring. Run now if you are near.
I’ve uploaded ISO and IMG files for DragonFly 4.6.1, so they should be available for download at your local mirror. Note that there’s an uncompressed 4.6.1 ISO for those installing to a virtual server.
I don’t have it uploaded yet, but DragonFly 4.6.1 is tagged. Anyone with an existing 4.6.0 or earlier system can upgrade now. Use the 4.6 release instructions if you are unsure on how to upgrade. The 4.6.1 tag commit message has all the changes.
Little yesterday, lots today:
Your unrelated extra lazy reading: IFComp 2016 games, a selection.
A somewhat short week this week, for BSD.
OpenSSL in DragonFly 4.6 has been updated to 1.0.1u. It’s time for a DragonFly 4.6.1, to catch up on this and other updates since the 4.6.0 release. I plan to work on it this weekend.
That’s Bryan Cantrill, of Joyent, interviewed in BSDNow 163. Joyent has been a major supporter of pkgsrc, though I don’t know if many people realize that. There’s the regular news roundup too, of course.
It’s now possible to start up a vkernel(7) using a COW disk, meaning copy-on-write. One image can be used and reused for multiple vkernels without changing, and all disk activity goes to memory instead.
It looks like I summarized iwm(4) updates too early, cause Imre Vadasz added an actual powersave option. I’d like to see someone with a power meter do some before-and-after testing.
This week’s Lazy Reading came together in perhaps 10 minutes.
Your unrelated music video of the week: Danny Brown – When It Rain. The music may not be what you are used to, but I like how “damaged VHS tape” is being used as a visual design choice. (via)
This was an easy week to put together; there’s a lot of links this week. Last week was slow – maybe it was because of EuroBSDCon?
BSDNow 162 has an interview with Petra Zeidler of the NetBSD Foundation, the nonprofit organization that supports NetBSD-the-operating-system. Plus the usual news, the highlight for me being a link to an explanation of what ^d really does.
It’s been a quiet week, but there’s some activity: Imre Vadasz has been committing many improvements to iwm(4). They haven’t been standalone enough for me to build a post around, but the most recent enables a low-power scan mode.
Every third link is about old technology, and I swear it’s not on purpose.
Your unrelated comics link of the week: DHARBIN. I briefly met the artist at TCAF a few years ago; he looks exactly like how he draws himself. Here’s an affecting strip about pets and loss.
A relatively uneventful week, at least for BSD.
I’ll just say I did this:
cpdup -VV -v /var/hammer/usr/snap-20160928-0301/local/pgsql/data /usr/local/pgsql/
And managed to bring back my last year or so of RSS feeds and the like. Phew!
BSDNow 161 has sort of 2 interviews this week. has Allan Jude talking about his EuroBSDCon trip, plus Michael Shirk talking about Bro on FreeBSD. Also, lots of news items right on the BSDNow page.
If you had trouble getting your laptop’s touchpad to work under DragonFly, try again. (If you are running DragonFly-current)
Mark Sumter’s giving a talk on ZFS at tonight’s KnoxBUG meeting. Hurry! I should have posted this sooner but work tied me up today.
It’s now possible to build dports using LibreSSL instead of OpenSSL. Set SSL_DEFAULT in make.conf to the appropriate port name, and start building. Use synth for fastest results, of course.
LibreSSL will eventually become the default library. This is in addition to the previously-mentioned, already-completed in DragonFly 4.7, base system switch to LibreSSL.
I manage to avoid a topic this week, really. That’s good!
It’s the convention time of year!
BSDNow 160’s title is linked to Allan Jude being at EuroBSDCon, happening right now. (Groff is there too!) Episode 160 is available in any case, and I bet there will be some sort of interview(s) coming out of this.
For those running DragonFly 4.7, there’s new firmware for all iwm(4) devices. Also, you can get temperature readings off the iwm wireless device now, if I’m reading this correctly.
Tomohiro Kusumi is thinking about porting it. Follow the whole thread for details.
3D printing on DragonFly with a Fabrikator? Yep, it works. (from jh32 on EFNet #dragonflybsd)
Partially assembled while I was in some multi-hour conference calls at work.
I’ve never had as many hackathon links as I did for g2k16 over this week and last.
Roguelike Celebration, happening tomorrow (the 17th) in San Francisco. Normally this would be in Lazy Reading, but that’s too late. (via)
Matthew Dillon has added powerd, a utility that will automatically step down processor speed based on reported temperature. The range is configurable, and there’s some other nice-to-have features. This will save your CPU from melting, and probably also your thighs from being burned.
This week’s BSDNow has no interview, but some good links, including a meaty one about HTTPS implementation at NetFlix with FreeBSD.
karu.pruun has been trying to get a Macbook’s hybrid graphics card to work in DragonFly. He’s been working on a gmux driver, but it needs a framework like Linux’s switcheroo. If this topic interests you, help him out.
Bryan Everly wants to start a BSD User Group in Indianapolis, Indiana, in the US. If you are anywhere near there and would go (and you should; user groups are great), tell him.
Addendum: Near Chicago works too, as joshua stein pointed out.
I may have mentioned this in part before, but Matthew Dillon has a brief script to reload pf when an interface IP changes. I’m linking it here in case it’s useful in the future.
Recent changes for virtual machine support and the new powerd utility have been rolled into the release branch for DragonFly. They’ll probably be in the next point release, or you can rebuild a release machine now for immediate access.
Also mentioned in the update from Matthew Dillon, DragonFly-master users should upgrade carefully as DragonFly migrates to using LibreSSL in base, and dports-based LibreSSL in dports.
Happy birthday to my younger daughter.
BSDNow episode 158 has an interview with Diane Bruce about ham radio and Raspberry Pi hardware, plus the usual news.
The’Errata 793‘ issue is apparently a bug where an AMD CPU can hang under very specific circumstances. Sepherosa Ziehau has a fix – please try it if you have the appropriate hardware.
How long does it take to build all 24,000 packages in the DragonFly ports collection? Apparently about 22 hours on a dual Xeon machine (with I think 36 cores) or 48-core Opteron. This is with synth. I used to measure pkgsrc builds in weeks.
DragonFly now has version 2.4.2 of LibreSSL and uses it in base. Ports may still link to OpenSSL, though – it’s still built by default, though make.conf can be configured to prevent that.
NYCBUG is meeting tomorrow night, with George Neville-Neil presenting DTrace work used as college-level teaching material, and talking about more places it could be used. Go if you are near New York City, interested in teaching, or you know – BSD. It’s in a different location than the normal monthly meetings.
This post fleshed out at the last minute, between road trips.
A week of travel didn’t get in the way of links! RSS feeds are still fantastic tools for those who know how to use them.
I’m a day late posting this because of travel, but: BSDNow 157 has an interview with Richard Yao about ZFS (on Linux?), and more story links. I found the “NetFlix and Fill” article link interesting – those are BSD appliances they are talking about that eat so much of the Internet’s traffic.
This makes sense once you think about it: copy-on-write filesystems (like Hammer2 and ZFS and probably others) actually do nothing when “zeroing” out filespace.
DragonFly-master (i.e. 4.7) now disables DSA keys by default. If you are using a DSA key for SSH/SFTP/whatever, you should change it anyway. Otherwise, it won’t work without workarounds after your next 4.7 upgrade, or by the time of the next DragonFly release.
GCC has been updated by John Marino from 5.3 to 5.4 in DragonFly – the 5.4 closed bug list on the GCC site is a good way to find out the benefits.
KnoxBUG’s next meeting is tomorrow night, and Mark Sumter is presenting on ZFS. Visit if you are near Tennessee.
Enjoy! I am going to have irregular network access over the next week, so this may be the only post for several days.
I don’t know how I ended up with 3 pfSense items to lead with – it just happened.
It’s been a very slow news week, but at least there’s a new BSDNow episode: The Fresh BSD Experience. There’s an interview with the FreeBSD Foundation intern, Drew Gurkowski, and a lot of ARM news.
Accidental nostalgia theme!
For once, I’m not working on Saturday, so even though this is last minute, at least I’m not in a race with the clock.
There’s been multiple reports of pulseaudio causing problems for DragonFly users. It would get pulled in as a dependency, and audio would suddenly stop working. Uninstall, and audio is fine. John Marino has removed it from dports, to prevent that exact problem.
BSDNow 155: no Allan, but an interview with Myke Geiger about using FreeBSD in an ISP role, and a bunch of news items.
There’s been a number of commits lately around higher optimization levels for your DragonFly kernel. It looks you can even set it systemwide. Boot code remains at -O; any higher level will make it explode. Is this safe? I have no idea!
If you are on DragonFly-current, AKA DragonFly 4.7, make sure to perform a full buildworld on your next upgrade. Tomohiro Kusumi changed a Hammer ioctl, and the buildworld is needed to keep everything in sync.
A manageable batch of links this week.
Your unrelated link of the week: Spaceplan. A clicker game, and very pretty. (via)
The Lumina release is the highlight of the week.
It’s a good week to learn: BSDNow 154 has no interview, but a lot of tutorials, including ones on GhostBSD, Enlightenment, Steam on FreeBSD, and so on.
The last bits of Linux emulation have been removed from DragonFly. It’s 32-bit, so it’s been unsupported since DragonFly went to 64-bit only with the 4.0 release. Also, some other 32-bit only items are gone, including the cs, ep, ex, fe, and vx network drivers. It’s almost impossible that anyone was using it, but it’s notable because that’s some… 15-20k lines of code gone? Removal of unused code is also positive.
Alex Merritt noticed that one of the new characteristics of DragonFly 4.6 was “improved IPI signalling”. He asked about benchmarks, Sepherosa Ziehau pointed at tools, and Matthew Dillon provided some results.
Because this always happens just after I create a DragonFly release, there’s a new version of OpenSSL. However, this is for version 1.0.2. 1.0.1 is what’s in the release, and it’s supported through the end of the year.
OpenSSH has a major version bump in DragonFly, to 7.3p1. This means some features – specifically patches for High Performance Networking – are no longer there, and you’ll get an error if your config file requires them. Either remove the options from your config, or install OpenSSH from dports.
Did you know that ACPICA has its own internal ‘coding language’, called AML? I did not, but it’s in DragonFly now in any case. Every program eventually grows big enough to read email, and every specification eventually includes its own programming segment.
If you’re one of the people who can easily read ‘systat -vm’ output, the data presented there has been modified. If you’re not one of those people, it’s a good way to monitor system health.
Getting esoteric this week.
Your unrelated link of the week: Mea Culpa. (via)
Garbage 37 is out, with talk about their format and timing, OpenBSD material, and more Chromebook discussion.
Here is some coverage of the DragonFly 4.6 release, which may be interesting to read because of the comments: Hacker News, Hacker News again, and lobste.rs.
A reaction to the initial creation of DragonFly I never saw before, and Matthew Dillon’s followup. (via)
I like the summary in the very first comment of this story on DragonFly removing page-zeroing.
It’s Thursday, so that means BSDNow 153, with a title inspired by the lead news item, “my int is too big”. (No, not spoon, int.) No interview this week, but lots of links.
Thanks to a reminder from IRC user ‘cgag’, I’ve put an uncompressed ISO image of DragonFly 4.6 up on the main site. It’s linked on the download page, and should be available within 24 hours on the mirrors. If you are buying service from a virtual host provider, and can install an operating system directly from a downloadable URL, this is for you.
After some testing of different ways to pre-zero out memory pages, Matthew Dillon came to the conclusion: page zeroing doesn’t matter any more. The idea dates all the way back to CSRG, and he’s removed it from DragonFly.
DragonFly 4.6 is officially released! Download from your nearest mirror, or update your source files and build – my users@ email describes the steps.
If you are near New York City, NYCBUG’s InstallFest is happening just before 7 PM Wednesday at the usual Stone Creek bar meeting location. Go, see what strange hardware turns up.
A mix of hard thinking and jokes today.
Your unrelated video link of the week: Duelin’ Firemen.
